JOSIAH KIRBY, OF CINCINNATI, OHIO.

BUNG-CUTTER.

Specification of Letters Patent No. 24,310, dated June '7, 1859.

To all 'whom it may concern:

Be it known that I, JosIAH KIRBY, of the city of Cincinnati, in thecounty of Hamilton and State of Ohio, have invented a new and usefulImprovement in Machines for Cutting Plugs and Bungs for Barrels andDeck-Plugs for Vessels; and I do hereby declare that the following is afull, clear, and exact description of the construction and operation ofthe same, reference being had to the annexed drawings, making a part ofthis specification, in which- Figure l is a perspective view and Figs. 2and 3 cutter sectional views in which same letters refer to same parts.

I construct the frame of my machine as shown in the drawings and modelabout siX ft. high two ft. deep from front to rear and about three ft.wide at the base and two ft. wide at the top, but this form of frame maybe changed to any other which may be made to suit the mode of cuttingand compressing the bung and is therefore not essential.

I give motion to my machine by means of crank shaft thrown across thetop of frame provided with pulleys and fly wheel and secured in itsproper position by pillow block securely bolted to the frame. In cutting and compressing the bung I use two plungers, one for cutting andthe other for compressing. The plungers are made to work perpendicularlyin the center of the front frame one by means of a cam on end ofshaft'and the other by crank on shaft, as seen in the model anddrawings. The cut-ter lies fastened in the lplunger at A Fig. l.

The lumber of which the plug is to be made is first sawed offI to thelength required for the plug and fed in at K by means of feeder J whichis made to move the strip forward to 4the cutter by arm J attached to A.The cutting plunger is made to raise and lower by means of an oval cam Ion end of shaft P which is made with a rim projecting from its innerface toward the frame and is connected to plunger by a hook as seen atA, Fig. 3. The cutter is brought down on the strip and cuts the plugoft', which remains in the cutter and is taken up with it the distanceof the stroke where it rests until the slide C is brought out under themouth of the cutter by means of lever E moved by cam E on back end ofshaft. At

this moment while the plunger is resting the plug is forced out of thecutter into the compressing boX by drag rod a, connected with rod B anddriven down by flange I on cam I. The slide C now moves back carryingthe plug in the compressing die and rests under the compressing plungerF, which is brought down on to the top of the plug, so as to force itinto the die and point or bevel the lower end by means of pressure fromthe crank which is connected to plunger by pitman F. The plug being madeit is raised out of the die rod G which runs through bracket of frame Dand which ismade to raise by rod and lever H I-I, with ,arm or plungerF, as seen at b l), Fig. 1.

When the plug is raised to the top of the die it is knocked off into thebarrel by rocker L, which is made to move back and forward by the motionof F after the plug has been rocked off the boss on rod IFIv at c, Fig.2, strikes against a beveled place on the frame at e, Fig. 2, and isthrown off of hook b and descends to its position to allow the slide Cto come forward to receive the neXt plug from the cutter.

I do not vclaim the cutter as used in the plunger nor do I claim themode of compressing the upper end of the plug or bung as used in mymachine patented 1848, that mode being to point or bevel, the perfectend being the lower end which is necessarily imperfect from being eatenoff when the timber is cross grained, as the head of the plug, but

1. The mode of pointing the lower or lastend cut of the plug or bung byforcing it into a separate die made and used substantially and for thepurpose as described.

2. I also claim the mode of lifting the plug out of the die after it hasbeen compressed, by means of rod G when operated in the manner and forthe purpose described- SJI also claim the mode of driving the plug outof the cutter into the compressing die by a movable rod as at a, Fig. 3,when operating in the manner and for the purpose described.
